| colspan="2" style="width: 908px; text-align: left; background: white;" |Since the change of the GNSS antenna is visible visually on PCB, in order to avoid problems at the customs of certain countries, we suggest informing the relevant authorities about the change of the GNSS antenna as soon as possible. The new GNSS antenna provides an equivalent track quality and performance level, as verified through testing. Testing results:

'''*'''''Mounting conditions'' - device position under the hood from a poor location (thick metal layer above device) to an excellent location (thin metal layer above device) <br>
'''**'''''Avg. Difference from precise track'' - measured by comparing positioning data from devices and RTK (Real-time kinematic positioning) system data which is considered precise data. The smaller avg. difference from precise track, means better track quality.
